Trans-2,3,13,14-tetradehydro-9-deoxy-9-methylene-ω-aryl-PGF compounds

ABSTRACT

The present specification relates to novel 9-deoxy-9-methylene-trans-2,3-didehydro-PGF compounds with improved pharmacological properties. While these compounds are useful in inducing a wide variety of prostaglandin-like pharmacological effects, they are specifically useful as regulators of procreation and fertility.

The present application is a divisional application of Ser. No. 893,771, filed Apr. 5, 1978, now U.S. Pat. 4,165,436, issued Aug. 21, 1979.

The present invention relates to prostaglandin analogs, for which the essential material constituting disclosure therefor is incorporated by reference here from U.S. Pat. No. 4,165,436. 

I claim:
 1. A prostaglandin analog of the formula ##STR1## wherein Y₂ is --C.tbd.C--; wherein M₁ is ##STR2## wherein R₅ is hydrogen or methyl; wherein L₁ is ##STR3## wherein R₃ and R₄ are hydrogen, methyl, or fluoro, being the same or different, with the proviso that one of R₃ and R₄ is fluoro only when the other is hydrogen or fluoro;wherein g is 4, 5, or 6, wherein Z₃ is oxa or --(CH₂)_(h) --, wherein h is zero, one, two, or three; wherein T is chloro, fluoro, trifluoromethyl, alkyl of one to 3 carbon atoms, inclusive, or alkoxy of one to 3 carbon atoms, inclusive, and s is zero, one, 2, or 3, the various T's being the same or different, with the proviso that not more than two T's are other than alkyl, with the further proviso that Z₃ is oxa only when R₃ and R₄ are hydrogen or methyl, being the same or different; and wherein R₁ is hydrogen, alkyl of one to 12 carbon atoms, inclusive, cycloalkyl of 3 to 10 carbon atoms, inclusive, aralkyl of 7 to 12 carbon atoms, inclusive, phenyl, phenyl substituted with one, two or three chloro or alkyl of one to 3 carbon atoms, inclusive, or a pharmacologically acceptable cation.
 2. A prostaglandin analog according to claim 1, wherein Z₃ is

    --(CH.sub.2).sub.h --.
